* Relax the conversion rules for Objective-C GC qualifiers aDouglas Gregor2011-05-081-0/+7
| | | | | | | | | | | | | | | | | | | | | | bit by allowing __weak and __strong to be added/dropped as part of implicit conversions (qualification conversions in C++). A little history: GCC lets one add/remove/change GC qualifiers just about anywhere, implicitly. Clang did roughly the same before, but we recently normalized the semantics of qualifiers across the board to get a semantics that we could reason about (yay). Unfortunately, this tightened the screws a bit too much for GC qualifiers, where it's common to add/remove these qualifiers at will. Overall, we're still in better shape than we were before: we don't permit directly changing the GC qualifier (e.g., __weak -> __strong), so type safety is improved. More importantly, we're internally consistent in our handling of qualifiers, and the logic that allows adding/removing GC qualifiers (but not adding/removing address spaces!) only touches two obvious places. Fixes <rdar://problem/9402499>. llvm-svn: 131065

* Modify some deleted function methods to better reflect reality:Alexis Hunt2011-05-0617-38/+44
| | | | | | | | | | | | | | | | | | | | - New isDefined() function checks for deletedness - isThisDeclarationADefinition checks for deletedness - New doesThisDeclarationHaveABody() does what isThisDeclarationADefinition() used to do - The IsDeleted bit is not propagated across redeclarations - isDeleted() now checks the canoncial declaration - New isDeletedAsWritten() does what it says on the tin. - isUserProvided() now correct (thanks Richard!) This fixes the bug that we weren't catching void foo() = delete; void foo() {} as being a redefinition. llvm-svn: 131013
* Don't emit nsw flags for vector operations; there's basically no benefit, ↵Eli Friedman2011-05-061-7/+4

* Add an implementation of thunks for varargs methods. The implementation is ↵Eli Friedman2011-05-063-46/+153
